Should I use VARCHAR or TEXT MySQL?

Some Differences Between VARCHAR and TEXT The VAR in VARCHAR means that you can set the max size to anything between 1 and 65,535. TEXT fields have a fixed max size of 65,535 characters. A VARCHAR can be part of an index whereas a TEXT field requires you to specify a prefix length, which can be part of an index.

Should you use TEXT or VARCHAR?

TEXT has a fixed max size of 2¹⁶-1 = 65535 characters. VARCHAR has a variable max size M up to M = 2¹⁶-1 . So you cannot choose the size of TEXT but you can for a VARCHAR . The other difference is, that you cannot put an index (except for a fulltext index) on a TEXT column.

What is the difference between BLOB and TEXT data type in MySQL?
